Happy Pi Day!

Do you know that today is celebrated as Pi Day? It's a new information for me too!

Pi Day is celebrated on March 14th (3/14) around the world. Pi (usually written as the Greek letter 'π' - is the ‘circle constant’) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.

Celebrated in countries that follow the month/day (m/dd) date format, because the digits in the date, March 14 or 3/14, are the first three digits of π (3.14), Pi Day was founded by Physicist Larry Shaw in 1988.

Because everyone should be able to enjoy a fun mathematical holiday, people in countries that follow the day/month (dd/m) date format honor pi on Pi Approximation Day. The date of Pi Approximation Day - July 22 - when written in the day/month format or 22/7 corresponds to the fraction (22/7) that pi is usually depicted as.

There are many other days during the year when one can honor pi. Some of these are:

• March 4: The day marks the passing of 14% of the 3rd month of the year.
• April 5: By this day, 3.14 months of the year have passed.
• November 10: The 314th day of the year (November 9 in leap years)

Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.

 

Pi is an irrational number, meaning it cannot be expressed as a fraction, and its decimal representation never ends and never repeats.

There are many ways to celebrate Pi Day, including consuming large amounts of its delicious homophone, pie. But a handful of people take their admiration further, by reciting tens of thousands of digits of pi from memory.

In 1981, an Indian man named Rajan Mahadevan accurately recited 31,811 digits of pi from memory. In 1989, Japan's Hideaki Tomoyori recited 40,000 digits. The current Guinness World Record is held by Lu Chao of China, who, in 2005, recited 67,890 digits of pi.

Despite their impressive achievements, most of these people weren't born with extraordinary memories, studies suggest. They have simply learned techniques for associating strings of digits with imaginary places or scenes in their minds.

For many of these memory champions, the ability "to remember huge numbers of random digits, such as pi, is something they train themselves to do over a long period of time," said Eric Legge, a cognitive psychologist at the University of Alberta in Edmonton, Canada.

Well, I guess now you are like "Ohh... really? I just know it!" Hehehe

Anyway, my life goes a bit hard this week. A lot of stuff to do. A little time to reflect with myself and even to talk to God. I'm so confused, sometimes I get headache. Now I'm trying to put my best in the college and lean on God. I'm so thankful that I can pass those busy days last week. It's only by His grace obviously! I know I am nothing without Him. That's why it's very important to always pray to Him and surrender our life to Him. I hope you guys have a great week and may everything that you do can please Him. See you in next post :)
